In order to display the Era the date belongs to AD or BC for a date in Java you need to make use of the SimpleDateFormat class with the date pattern that makes use of G
Example: Display Era in Java date
package com.company;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class Main {
public static void main(String[] args) throws ParseException {
String beforeChrisDate = "22 01 -2020";
String annoDominiDate = "22 01 2021";
DateFormat simpleDateFormat = new SimpleDateFormat("dd MM yyyy");
DateFormat simpleDateFormatEra = new SimpleDateFormat("dd MM yyyy G");
Date bcDate = simpleDateFormat.parse(beforeChrisDate);
Date adDate = simpleDateFormat.parse(annoDominiDate);
System.out.println(simpleDateFormatEra.format(bcDate));
System.out.println(simpleDateFormatEra.format(adDate));
}
}
Output:
22 01 2021 BC
22 01 2021 AD
As you can see in the above example, we first created a string that holds the date in dd MM yyyy format, then we converted it into a Date object and while displaying the date we used the format dd MM yyyy G, the negative year is displayed with suffix BC - Before Christ and positive year is displayed as AD - Anno Domini.
